My Doomsday Territory

Chapter 39: Krypton crystal

Views:

The demon tide comes and goes in a hurry, like a responsible courier, leaving behind love and warmth here.

Fortunately, as a universal currency in the new century, the strength of source crystals exceeded Tang Yu's expectation. Despite the endless destruction of artillery and arrow towers, these source crystals were still intact, and even because of these demonizations, they were still intact. The beast's carcass was destroyed and broken into pieces, so it was quite easy for Source Crystal to clean it up.

It wouldn't be bad to do this again in the future... What an egg!

He still felt sorry for those materials. Not only could they be used to make equipment, but more importantly, they were going to Lindong soon. There was always a market for a shelter as big as Lindong, right? Tang Yu was still looking forward to making a fortune.

In addition, there were some powerful demonized beasts with relatively well-preserved materials. Tang Yu ordered people to collect these materials while he counted the profits from this battle.

The demonized beast brought so many source crystals, so the money must have been earned, but this wave was not without losses.

Just to build these defensive buildings, regardless of materials, Source Crystal cost two thousand. Not only that, but energy is also consumed when defending against building attacks.

Where does this energy come from? Of course it came from source crystals. Tang Yu stored some source crystals in the small warehouse of the castle. This was consumed for defensive buildings. Otherwise, he would not have waited until now to build defensive buildings.

Tang Yu remembered that there was a building called an energy patio in the third-level territory, which could absorb free source energy in the air to replenish energy for defensive buildings. Probably before this building was built, these defensive buildings were all big players.

After all, he had made money. Tang Yu was in a very happy mood. In addition, there were already a lot of source crystals from the previous plunder at the source crystal mine. Before going to Lindong, these source crystals must be spent on the most appropriate way. place.

The other survivors were also in a happy mood.

This is the aftermath.

The city gate has been reopened, and some brave survivors stepped forward to view the corpse of the demonized beast up close.

"Oh my god, it's so big! Such a big demonized beast is dead!"

Ordinary survivors have never come into close contact with a demonized beast. Immediately, a survivor poked at it and found that it was really hard.

So many terrifying demonized beasts attacked, but they were successfully dealt with by the shelter.

A shelter for less than a hundred people.

Who would dare to believe such a record? Although most of this is due to Director Tang, without hindrance, this can become their bragging capital!

In the past, many ordinary survivors could only eat and wait to die every day, but it is different now. As long as they work hard, they can eat well every day. Now they know the power of the shelter, and even the demonic tide can't do anything about it. In the end of the world , other than a large shelter, is there any safer place than this

Unknowingly, the survivors felt a sense of belonging to the shelter and sincerely felt lucky to be here.

… …

After the demon tide ended, Tang Yu was not idle either. He left the outside matters to Chen Haiping and Luo Zhe, while he came alone to the back of the castle, the area used to build system buildings.

Among the core four-piece set, the tavern, workshop, and market have all been built, leaving only the final research institute.

Tang Yu asked No. 1 and No. 2 to transport materials back and forth, and finally saw that the construction conditions on the panel were met.

"Constructing the research institute consumes one thousand units of source crystal, one hundred units of wood, three hundred units of stone, and three hundred units of iron."

Just like the previous times, a three-story building soon appeared in front of Tang Yu.

Go inside.

There are all kinds of research equipment in the institute. Tang Yu looked around and recognized only a few of them. It was just a beaker, the kind used in high school experiments. He still had some impression... Maybe they just looked alike, anyway. It's a cup.

These are not important. What is important is the function of the institute.

As an important functional building, the institute has its own indispensable position.

Research and development drawings, strengthening drawings, transformation drawings, etc. are all functions of the research institute. In theory, as long as it has sufficient knowledge and source crystals, the research institute can develop the desired drawings on its own.

This is very far away.

Currently, the research institute's level is low, and Tang Yu is not prepared to invest too much source crystals. He mainly uses its function to transform blueprints.

For example, for a basic long sword, the workshop only comes with this kind of blueprint, which is very inhumane. What if someone else wants to use a knife or other weapons? !

Transforming the blueprint means changing the long sword blueprint into a sword blueprint. Of course, the level remains the same and it is still the basic equipment of one rune, but it has more applicability.

Not only that, the basic material used in the long sword drawings is iron. After the drawings are modified, demonized beast materials can be added, such as demonized beast claws, bones, etc. Although the level of the drawings has not changed, the materials used are better and the production The weapons that come out are naturally more useful.

Tang Yu first modified the sword blueprint, and then designed a whiteboard shield blueprint without runes and a firearms bullet blueprint. With the blueprints, they can be manufactured in batches in the workshop.

After completing the research institute, he no longer had to build it, and instead came to the market.

He didn't choose to build a system building anymore, not because it was unnecessary, but... it was futile.

In order to go to Lindong Sanctuary, you must first get a scroll of return to the city. This thing obviously has a high chance of being refreshed in the early stage, but he just never got it. For this reason, the market was upgraded to level 2 yesterday, and the counter was changed from ten The number of refresh slots increased to twenty. However, even after several refresh attempts, there was still no scroll to return to the city.

One refresh is five hundred units of source crystals. Even though he is a big boss who has held tens of thousands of source crystals, he dare not continue after spending several times. This is no longer krypton crystals, but krypton life...

Tang Yu felt that he had made a mistake yesterday. He happened to have solved the moths in the shelter today and defeated a wave of demonized beasts. He must be lucky. As long as he draws the scroll of returning to the city and makes some preparations, he can set off. Lindong.

First of all, he took a look at the goods sold out today. Some of them were quite high in value, but they were too high and he couldn’t afford them. Since he had several zeros in the back, he thought he would have to wait for a real boss with over 100 million source crystals to buy them. Take a look at those things, otherwise your heart will hurt and your eyes will hurt.

Can't afford to be hurt. Can't afford to be hurt.

brush!

Starting from the first grid, the products are refreshed one by one.

Intermediate wood resource package (five hundred units) price: forty-nine source crystals.

Number remaining: five.

Feilian (weapon) production blueprint price: 3,000 source crystals.

Number left: one.

The price of fruits from another world: one hundred source crystals.

Notes: Very delicious fruit.

Number remaining: fifty.

Skill Runestone (Burn the Sky and Boil the Sea) Price: One million high-purity source crystals.

Number left: one.

The first refresh, as expected, didn't even see the shadow of the scroll to return to the city, but there were some good things, such as Feilian weapon manufacturing blueprints... If the source crystals were abundant, Tang Yu would definitely buy many of these blueprints. If you buy more, you won’t suffer a loss, and the value will be preserved. Even if it doesn’t work, the research institute can use it to research and synthesize new blueprints.

It's a pity that his source crystals are very insufficient.

For other things, like fruits from another world, Tang Yu can only say that more and more weird products have appeared after the market rises, but the probability of getting high-end items is also much higher, such as skill rune stones... This is still a market It was the first time that skill rune stones were generated, but Tang Yu ignored it calmly.

one million? High-purity source crystal

He can't even get one million, let alone high-purity source crystals. He's never even heard of it!

After losing all his money for the first time, Tang Yu took a deep breath and said, "Don't panic, don't panic. I even bought a million worth of gadgets, which shows that I am still the European Emperor in essence. A few return scrolls are nothing. !”

… …

A few minutes later, Tang Yu turned pale, gasping for air, and sweat dripped from his face.

He couldn't remember how many times he had refreshed, but the few scrolls of return to the city did not appear. Could it be that the value of the scroll of the return to the city was too low, so it belonged to the category of non-chiefs and the European Emperor could not get it

What's even more annoying is that after so many times, I still get lucky and get some good things. The price of these things was moderate, and they were of great help to him at this stage. In short, they were so tempting that he couldn't help but just... buy them.

He browsed several times in succession and bought a lot of things in the process. In just a few minutes, the source crystal in his hand shrank by more than half.

This is simply worse than a certain treasure!

After all, I bought what I wanted most, but what about this broken market? She always gets some glamorous bitches to seduce him. If this continues, without buying the scroll to return to the city, I'm afraid I'll have to go back to the poor days before.

That does not work!

Tang Yu returned to the castle, bathed, changed clothes, and burned... Burning paper, but couldn't find the incense, so he could only use paper rolled into an incense shape instead.

Return to the market again.

"Sanqing, Lord Buddha, Goddess of Luck, Lord of the European Emperor, Senior Bai... Whoever it is, please give me the power to draw the scroll to return to the city!"

Tang Yu closed his eyes and opened them.

Put your fingers together to form a sword.

brush!

Starting from the first product column, the white brilliance swept across, and the products had changed into a completely new look.

The bones of high-level demonized beasts.

Spring water containing powerful vitality.

Describes the basic knowledge of using source capabilities.

Energy level beam gun production drawings.

A scroll that increases the probability of summoning...

They are all top quality!

Tang Yu sadly discovered that it seemed that it was time for heavy bleeding again.
